A pH of 4 indicates the acid is moderately acidic. It has more hydrogen ions than a neutral solution but fewer than a very acidic solution.
Water does, as it has a pH of 7. It's also the most "acidic" base
all the substances that ranges less than 4 in a ph scale
Ethanoic acid is vinegar, it can be diluted to be pH 4 or 5, it can also be very concentrated to be 1 or 2. Most ethanoic acids are 4-5 in pH.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
A pH of 1 is most acidic. The acid in your stomach is about a 2 and it is strong enough to burn a hole in a rug.

Acids generally have a pH ranging from 1 - 6. pH 1 being the most acidic, and pH 6 being the least acidic. eg, hydrochloric acid, nitric aicd, sulfuric acid has a pH of 1. Ethanoic acid has a pH of 3.

Whether something is acid or base the strength of that solution is measured by the pH scale. 0 (zero) is the most acid and 14 is the most base. distilled water measures 7 and is completely neutral. Ammonia is an example of a base and is usually measured at a pH of 11.6. So the answer to your question is that an acid has a positive pH. There is no such thing as a negative pH.

The most effective way to maintain a stable pH is by the use of a buffer. These are solutions of a weak acid or a weak base, and the conjugate base or acid, adjusted to the desired pH.

The most effective pH for extracting aqueous acetic acid into hexane is typically around pH 2-3. At this pH range, acetic acid exists predominantly in its undissociated form, which is more soluble in hexane compared to its dissociated form. Adjusting the pH to this range can help improve the efficiency of the extraction process.
The pH of muriatic acid, also known as hydrochloric acid, is typically between 0 and 1. It is a strong acid with a very low pH due to its ability to dissociate completely in water, releasing hydronium ions.
All acids are corrosive, but to what - that is the real question. It is really a matter of PH. PH is the measure of acid or alkalai. even alkalais are "corrosive", just in a different way. The corrosiveness depends on the PH of the acid and what it is being put on. if acid was corrosive to everything , then you couldn't transport it in anything because nothing would contain it. Hydrochloric acid is VERY corrosive(ph=1), generally speaking to almost all substances - but not glass, or most plastics. ethanoic acid (vinegar)is very weak (ph=3) Neutral PH is 7, the most acid is 1, the most alkalai is 14 Oven cleaner is an alkalai about PH=12 combining an acid at ph=1 with an alkalai=14 would yield a neutral PH - Theroetically of course - this would not be a good experiment unless you know what you are doing!
